  • Process of producing sugar composition comprising D-psicose and D-allose via strong alkaline isomerization of D-glucose/D-fructose or alkaline pre-treatment of D-glucose/D-fructose followed by isomerization in the presence of a basic ion exchange resin
    Patent number: 9109266
    Abstract: Problems Development of a process of producing inexpensive and safe hexose and compositions of the same. Means for Resolution A process of producing a sugar composition comprising a definite amount of an target hexose, comprising treating a starting liquid sugar material comprising a starting sugar material hexose or a mixture comprising hexose in a system in the presence of one or more types selected from the group consisting of basic ion exchange resins, alkalis and calcium salts to initiate an isomerization reaction as an equilibrium reaction to transform the starting sugar material hexose to the target hexose to prepare a sugar mixture comprising a definite amount of the target hexose and having a sugar constitution different from that of the starting sugar material, and hexose compositions containing D-allose and D-psicose and the use of the hexose compositions.

  • Application of D-psicose to suppression of abnormal circadian increase in blood glucose level
    Patent number: 8071558
    Abstract: A novel use of D-psicose (for suppressing the abnormal intra-day increase of blood glucose level) is provided. A composition containing D-psicose as the active component and for use in suppressing the abnormal intra-day increase of plasma glucose concentration. The composition is a composition in blend with D-psicose and/or a derivative thereof.
